[2] The copper woolly bat is a small microbat, with a forearm length of 30–33 mm (1.2–1.3 in) and weight of 4.0–4.5 g (0.14–0.16 oz).

The uropatagium (flight membrane between the hind limbs) lacks a fringe of hair, which can distinguish it from some other African Kerivoula.

[3] The copper woolly bat is insectivorous, foraging for its insect prey in cluttered rainforests.

It likely favors smaller arthropods and those that are soft-bodied, as its teeth and skull are incapable of generating a high bite force.

[3] The copper woolly bat has been documented in the following countries: Cameroon, Democratic Republic of the Congo, Ivory Coast, Guinea, Kenya, and Liberia.
